A new 2600mAh battery from Xtar, this time it is called 18650, instead of 18700. This does not mean it is 5 mm shorter, it is only about about 1 mm shorter.

great battery review as always, thanks!

 

i don't like the xtar black battery wrapper. the material. it gets brittle after 1 year and chips after repeated insertions in flashlights. i prefer the transparent wrappers of generic protected cells. thicker and more wear-resistant. softer so to speak.

sure enough, after many many years, any plastic material becomes brittle, call it "aging" of materials.

*FMI* i got 4 i/o sh

Luckily it is easy and cheap to fix.

It is not all black wrappers that has problems, most of my batteries with black wrapper are intact, even if they are a couple of years old.
